Coaxial cable with hard copper wire as the core, outsourcing a layer of insulation materials. The insulating material is surrounded by tightly woven network conductors and covered with a protective material. There are two widely used coaxial cables. One is the 50 ohm cable, which is used for digital transmission. The other is the 75 ohm cable, used for analog transmission, or broadband coaxial cable. This distinction is made for historical reasons, not for technical reasons or manufacturers.

处理器(CPU)：刚跟大家讲过，需要提醒的是MCS-51的CPU能处理8位二进制数或代码。CPU是单片机的主要核心部件，在CPU里面包含了运算器、控制器以及若干寄存器等部件给成。内部数据存储器(RAM)：MCS-51单片机芯片共有256个RAM单元，其中后128单元被专用寄存器占用(稍后我们详解)，能作为寄存器供用户使用的只是前128单元，用于存放可读写的数据。因此通常所说的内部数据存储器就是指前128单元，简称内部RAM。
